3 Claims.

My invention relates to improvements in oil stove wicks, and it consistsin the combinations, constructions and arrangements herein described andclaimed.

One objection to the use of oil stoves is the fact that the ordinaryfabric wicks burn or char, and this makes an uneven flame. Itnecessitates the trimming of the wick frequently. In order I to obviatethe burning of the wick various forms of refractory wicks have been usedsuch as those made of asbestos. An asbestos wick, however, does not havethe capillary attraction for oil that a wick such as a cotton wick wouldhave,

I and the feeding of the oil is therefore retarded,

some times to such an extent as to decrease the flame to a point beyondnormal.

Another difficulty experienced with asbestos wicks is that if food whichis being cooked boils over and spills on the wick the attempt to removethe food causes the disintegration of the wick, since the asbestos wickcannot stand the same handling that the ordinary fabric wick can stand.

A further objection to the use of asbestos wicks is that the handling oradjustment of the wick will often cause the fibers to loosen up to suchan extent that the wick soon becomes Worthless for use.

An object of my invention is to provide a refractory wick which isstrengthened by reinforcing layer partly made of metal, thus preventingthe disintegration of the wick due to handling or adjustment and greatlyprolonging the life of the wick.

A further object of the invention is to provide a wick which will not beconsumed but which has a layer of fabric whereby the oil is more readilyconducted to the upper portion, thus obviating the objection found withthe ordinary asbestos wick which does not have this fabric layerextending substantially to the flame.

A further object of the invention is to provide a wick of the asbestostype in which the upper portion of the wick will not disintegrate asreadily since it is supported by the reinforcing layer.

Other objects and advantages will appear in the following specificationand the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings forming part ofthis application, in which:

Figure 1 is a sectional view through a burner sleeve with my improvedwick applied thereto.

Figure 2 is a side elevation of the sleeve and wick shown in Figure 1.

Figure 3 is a plan view of the part shown in Figure 1. I

Figure 4 is an enlarged cross sectional view of 61? the wick showing thevarious layers and the holding member for the burner.

Figure 5 is a plan view of a modified form of the wick.

Figure 6 is an edge view of Figure 5, and,

Figure. 7 is an enlarged cross sectional view of a portion of the wick.

Referring now to Figure 1, I have shown therein a wick sleeve 1 andretaining members 5 which are spaced apart from the sleeve 1 and whichare to be found in any ordinary burner. The wick is held between thesemembers. It consists of layers 2 of asbestos fabric. Between theselayers 2 is an oil conducting layer 3 made of cotton or similar fabric.A fourth layer con-v sists of a wire screen impregnated with asbestosfiber and flour. The impregnation may be made in any suitable manner asby 'applying a paste to the screen and then pressing and. drying it. Thescreen itself is preferably made of copper, although it may be made ofother metal. The layers are held together by copper staples 6. which aredisposed at intervals, as shown in Figure 1.

It will be noted that the oil conducting layer 3 and the reinforcinglayer 4 terminates short of the top of the wick, leaving a short length21: of the layers 'of the asbestos projecting beyond.

A wick constructed according to the invention will readily conduct theoil to the portion 2.1: so that there is a steady flow of oil. Thisinsures a steady flame and when the wick is adjusted to a certainposition the flame will remain steady as long as there is any oil in thestove. Should the food boil over and flow down on the wick, the removalof the food will not disintegrate the wick due to the reinforcementgiven by the layer 4. The latter layer also tends to strengthen the wickso that when it is handled or adjusted the asbestos layers will beprotected from bending or distortion, thereby increasing the life of thewick. The use of copper staples prevents the separation of the layers,and since the copper is not easily oxidized as would staples made ofiron, there is no danger of their giving away.

In Figures 5, 6, and '7 I have shown a modified form of the invention.In this form the layers I are all flat strips. As will be seen fromFigure no 7, there are two asbestos layers 2. These layers are heldbetween reinforcing layers consisting of copper wire impregnated withasbestos fiber and flour. In making the wick the reinforcing layer isbent around the bottom of the asbestos strips and brought up closely onthe sides thereof to form layers 7. The layers are held together bymeans of staples 8 along the edges of the wick. v i

In this form, as in the form'shown in Figures 1 to 4 inclusive, theasbestos layers are reinforced by the wire screen layer, but in thisform the fabric wick such as cotton, is dispensed with.

The outer layers with the wire screen form a protecting cover and alsoaid in conveying the oil, since the fibers with which thescreen visimpregnated carry the oil by capillary attraction.

I claim:-- I

tos fibers and flour, said cotton layer and said reinforcing layerterminating short of the upper end of the wick.
